HAIR` CURLER Filed Aug. 25, 1944 Patented Jan. 15, 1946 UNITED STATESPATENT OFFICE CURLEE Rudolf Krasberg, Chicago, Application Augusty 23,1944, Serialllrlo. 550,692 6 Claimsl (CL12m-T34) The. `present inventionrelates to hair curlers and more particularly to an improved hair curlerwhich will hold the curl from unwinding at any desiredl position on thestrand of hair.

Heretofore hair curlers of a type comprising a bar on which a curl. maybe WoundV have been provided with a suitable gripping member and apivotedv loop-shaped locking member for restraining uncurling of thestrand of hair Wound on the bar. Such type of hair curler usually uses ahollow bar which may be perfor-ated and which has a spring biasedgripping or clamping member for engaging the end` of a strand of hair tobewoundupon the bar inthe form of a curl. A loop-shaped. locking memberwhich is pivotally connected tothe bar restrains the curling motion butdoes not permit the curl to be wound tightly against the head of aperson since in winding it is not possible to judge With great accuracyhow many turns of the bar are required to form a. curl. Obviously av xedlocking or restraining member therefor may be a fraction of a turnremoved from a most desirable restraining position. Other types of haircurlers have been provided' with a hair pin like member inserted in thehollow bar, but such device is particularly disadvantageous when thehollow bar isof'the perforated type since it is diliicult to insert thehair pin like locking member into the bar since the perforated interiorof the bar does not readily permit the placement of the wire member inthe most desired restraining position. In` accordance with the presentinvention the above mentioned disadvantages are overcome byy providing ahair curler of the type having a barand a clamping or gripping memberwith a restraining member which is resiliently retained inthedesiredposition so as to have adequate inherent rotation resistingaction relative to the bar.

It,Y therefore* is an object of the present invention to provide animproved hair curler with a restraining or locking member which obviatescer-tain` disadvantages. ofthe devices-of the prior art;

Othery andl further objects of the present invention. subsequently willbecome apparent by reference tothe following description taken inconnection with the accompanying drawing wherein:

Figure 4- is a cross sectional View through the hair curler at rightangles to the longitudinal axis thereof at a time when a strand ofhairhas been formed on the curler and' tightened,y against the usersscalp, the locking member serving at this 4time to restrainltheuncurling action ofthe eurle er; and` Figure 5 is a cross sectionalkView of the curler similar to Figure 4., showing. the` locking memberreleased from the curl. so as to enable convem. ient longitudinalwithdrawal of the curler.

Referring to the drawing therev is shown in Figure 1Y a strand of hairIllwound` in the formy of a curl la upon a hair curler having a bar. I4'anda cooperating clampingv or gripping mem-, ber I6; A loop-shapedlocking member I8 is positioned so as to restrain the uncurling actionof the curl I2.

The details of the arrangementgenerally shown-x in Figure-1` will becomeapparent from Figures 2f and 3 from which it will be seen thatpreferably the bar I4 is of the hollow perforated type, in` which casethe gripping member IEm-ay-also be perforated. The gripping member I6:mayv be spring biased byra suitable spring Z'interposed. between alinger oper-ating portion 2'2 ofthe gripping member IB andthe body ofthe bar` I4. Oneend of the spring member 20 may be retained-inposit-ionbyengagement with an up-structure portion` 24 of the bar I t or someother simi-lar restraining arrangement which ofcourse will be apparentto those skilled'in the art. The gripping member` I6 isA pivotallysecuredto the body l2- by a suitable rivet member 26. The end olf; thebar I d extendsv an appreciable distance b eyondjthe end of the lingerportion I2-of the gripping' member I6 so as to providesuflicien-t lengthfor supporting a frictionally retained rotatable sleeve mounting member23 whichV is provided` with suitable-projectingportions 30 forpivotallysupporting the restraining or locking member- I8;

The sleeve 2 8' may have provided-at the interior thereof anannular-'recess 3 2 which isengaged-by a portion of a spring 311|,Vmounted Within the eX- tension portion of the bar I4; One end oftheiresilient member 34 engages the inner surface of the bar I4 and theother end'thereofv projects-L through an aperture 36 so that the endofthe springv mayY engage the annular recess 321701? the -supportingcollar or sleeve 28. The spring 34 therefore serves to frictionallyretain in position the sleeve 28 although by the application ofsufficient force the sleeve 28 may be rotated so as to position thelocking member I8 at any desired angular position relative to the barI4. The locking member I8 at a short distance beyond the pivotalconnection with the extensions 30 of the sleeve 28 is provided withinwardly curved portions 38 adapted to engage. oppositely arrangedrecesses. or slots 40 formed in the sleeve 28 for retaining the lockingmember I8 in thejlocking po sition shown in Figures l and 2.

During the time when the strand of hair IG is being wound into the formof a curl I2 on the bar I4 the locking member I8 is in its lookedposition as shown in Figure 2. In this position the locking member I8 isprevented from rotating with the bar I4 by the fingers of the operatorshand. In other words, while the operator turns a ilnger grip cap 42which is secured to one end of the bar I4 the Vother hand holds thelocking member I8 against rotation. During this operation the curl iswound around the bar I4 and the gripping member I6, as illustrated inFigure 4. Due to the fact that the bar or tube I4 is adapted to berotated relatively to the locking member or bale I8 the user may tightenthe curl against the scalp to any desired degree. Once the curl has beentightened in the positionshown in Figure 4 it will retain that positionand be prevented from uncurling by reason of the bale or locking memberI8.- It should be understood that while relative rotation between thetube or bar I4 and the baleV I8 takes place during theinitial'tightening of the curl, such rotation is continuouslycounteracted by the action of the spring 34 engaging the sleeve 28. Thisirictional engagement of the spring 34 with the sleeve 28 is suiiicientto prevent inadvertent or unauthorized uncurling of the strand after ithas been tightened against the users scalp in the position illustratedin Figure 4. Thus during the time that the curl is drying and being setit is. prevented from uncurling and loosening by the action of theresilient member or spring 34 upon the sleeve 28. The users scalpisindicated by dot and dash lines in Figures 4 and 5.

When it isdesired to release the curler it is only' necessary to pivotthe locking member or bale I8 away from the curl to the dotted positionillustrated in Figure l, thereby releasing the strand. In yFigure 5 thecurl is shown released from the bale I8 in position to permitlongitudinal withdrawal of thecurler. While in the disclosed embodimentthe strandV gripping member IG is formed with a `finger operatingportion 22 which is biased by the spring 20, it should be understoodthat in some instances this structure may be eliminated. -Under suchcircumstances the weight of the gripping member IG is suicientto effectthe initial gripping of the strancL-and the longitudinal withdrawal ofthe curler from the nished curl may be occasioned without the necessityof manually releasing the gripping member. In other words, the use of aspring biased or freely pivoted grippingmember is optional.
